\'Etude de performance des syst\`emes de d\'ecouverte de ressources

TL;DR

This paper evaluates the scalability and performance of P2P protocols Bonjour, Avahi, and Pastry for resource discovery in distributed desktop grid systems, focusing on registration and discovery times.

Contribution

It provides a comparative analysis of three P2P protocols' efficiency in resource registration and discovery within desktop grid environments.

Findings

Bonjour has the fastest registration time.

Pastry offers the quickest service discovery.

Performance varies significantly among protocols.

Abstract

The Desktop Grid offers solutions to overcome several challenges and to answer increasingly needs of scientific computing. This technology consists mainly in exploiting PC resources, geographically dispersed, to treat time consuming applications and/or important storage capacity requiring applications. However, as resources number increases, the need for scalability, self-organisation, dynamic reconfiguration, decentralization and performance becomes more and more essential. In this context, this paper evaluates the scalability and performance of P2P tools for registering and discovering services (Publish/Subscribe systems). Three protocols are used in this purpose: Bonjour, Avahi and Pastry. We have studied the behaviour of these protocols related to two criteria: the elapsed time for registrations services and the needed time to discover new services.
